7a619e6790 Dematerialize the source functions after we're done with them. This saves a bit

11cd3dd9fc Take out the debug info probe stuff. It's making some changes to 
the PassManager annoying and should be reimplemented as a decorator
on top of existing passes (as should the timing data).

few comments where none existed before. Also change a function's name to match
the current coding standard.

8243f2a6d4 Revert a series of commits to MCJIT to get the build working in CMake 
(and hopefully on Windows). The bots have been down most of the day
because of this, and it's not clear to me what all will be required to
fix it.

The commits started with r153205, then r153207, r153208, and r153221.
The first commit seems to be the real culprit, but I couldn't revert
a smaller number of patches.

When resubmitting, r153207 and r153208 should be folded into r153205,
they were simple build fixes.

0cbb33ea72 In erroneous inline assembly we could mistakenly try to access the

ce3a78be60 [fast-isel] Fold "urem x, pow2" -> "and x, pow2-1". This should fix the 271% 
execution-time regression for nsieve-bits on the ARMv7 -O0 -g nightly tester.
This may also improve compile-time on architectures that would otherwise 
generate a libcall for urem (e.g., ARM) or fall back to the DAG selector.

3f84548106 Add a ${pathsep} variable to lit that expands to : (or ; on win32). 
This is in braces so that it doesn't conflict with the existing %p.
It uses braces instead of parens because parens would have to be
regex-escaped.

f6bfe93d8f Based on this discussion: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20120305/138477.html 
1. Declare a virtual function getPointerToNamedFunction() in JITMemoryManager
2. Move the implementation of getPointerToNamedFunction() form JIT/MCJIT to DefaultJITMemoryManager.

de0e7fdcde Checking a build_vector for an all-ones value. 
Type legalization can zero-extend the elements of the build_vector node, so,
for example, we may have an <8 x i8> with i32 elements of value 255. That
should return 'true' for the vector being all ones.

8700c2d093 Teach instsimplify to gracefully degrade in the presence of instructions 
not attched to a basic block or function. There are conservatively
correct answers in these cases, and this makes the analysis more useful
in contexts where we have a partially formed bit of IR.

I don't have any way to test this directly... suggestions welcome here,
but I'm not seeing anything sadly. I only found this using a subsequent
patch to the inliner which runs instsimplify on partially inlined
instructions, and even then only on a quite large program. I never got
a reasonable testcase out of it, and anything I do get is likely to be
quite fragile due to requiring an interaction of two different passes,
and the only result being a segfault if it goes wrong.
